EARL-LIGHT,

Application illed September 24,

In the present state of the artof rear light construction forautomobiles, it is quite usual to combine in a single casing a. taillight and s stop light for use on. motor vehicles. someinstances a thirdor backing light has also been combined with the tail light and stoplight, each oi said lights being arranged in a separate compartment ofthe casing an having its individual reflector and lens. It lo is the object of the present invention to combine the three lights in a singleunit which is no lerger than that required tor the two lights, therebyreducing the cost of: manuiacture and of shipment, obtaining a more ispleasing appearance and simplifying the,

construction.

With this object in view, my invention con SISbSll'l the novelconstruction as hereinafter p set forth,

lin thedrawing: v Figure l is a vertical central section, Figure 2 is atrout elevation thereof "Figure 3 is a rear elevation thereof. A is theouter casing of the lamp which as me be oi any desired shape or design,but which is provided with only two rearwardly freeing light openings.The lower one of these light openings is for the tail light and isprovided with the usual red glass 13. The so upper opening istransparent pane C or if a color is used, one which will have the leasteffectin diminishing the intensity of the light passing there andthrough. D, E and F are three separate lamp bulbs respectively used forthe tail light, stop light and backing light. The bulbs D and E are botharranged in a portion of the case that is in rear of the lass B, but thebulb E is shielded against t e passo sage of light through said glass bya reflector G which will direct the rays upward or into the portionofthe casing in rear of the transparent panel 0. Within this portion ofthe casin is a concave reflector H so arrange 5 es to irect the raysfrom the bulb E outward through the panel C. The bulb F is arranged infront of the refiectorI-l and therefore its rays also may be directedoutward throu the panel C. To differentiate the stop lig t rays from thebacking light, a filteris arsror mom, AND naomuo mom: son

ranged intermediate the bulb E and the re fiector H. This, as shown, isthe glass I of any desired color which is mounted in a par- In tition Jthat separates the casing into compartments X and Y respectively in rearof the glass B and glass C.

moron The socket for the bulb F is in the reflector ior the bulb E is inthe re ilector G; and the latter is suspended from the partition J. Thesocket for the bulb D is in a bracket J depending from the reflector G.This bulb D is located sufiiciently for ward in the casing so that itsrays which pass out throughthe panel B will not be obstructed by thereflector G. There is also the usual transparent panel D beneath thebulb D tlirough which the light passes to thelicense ate.

The rear of the chsmg is provided with a socket K for the connector plugas shown and from the socket the contacts L, M and N lead to the bulbsD, E and F; The casing A. may be mounted upon any suitable supportingbracket or by any suitable clamping means such as the screws 0 Also theglass panels B and C are mounted in a suitable frame P and of anysuitable construction.

In use the bulb E may be controlled by a switch operated by the brakepedal as is usual for stop lights, and the switch for the bulb F may becontrolled by the gear shift lever so as thrown into reverse. each ofthe bulbs E and F passes outward through the same panel C butalternatively, because of their respective controls. Thus withoutincreasing the size of the casing over that required for the stop lightand tail light combination I have added the third light for backing.

the opening in front thereoi, including a detachably engaging the casingto be illuminated whenever this is- Thus the light from.

shining through provided reflector for directing a portion of the lightfrom the third bulb transversely into the space opposite the other ofsaid openings, 8. reflector for redirecting said light throng 5 thelatter openin and a filter arranged hetween said thir light and saidlast mentioned reflector for changing the character of light deliveredtherefrom.

2. A lamp comprising a casins having adio jacent light openings, lampbulbs arranged opposite the respective openings for delivering lightdirectly therethrongh, a third bulb arranged opposite one of saidoipenings, a reflector below and in front of t e third bulb preventingdelivery oflight from said third ulb through the last mentioned openinand directing light rays from said third bul to a point in rear of theother of said 0 nings, and a reflector above and in rear or one of thefirst mentioned bulbs for redirecting v the last mentioned light raysthrou h the other of said openings, said lamp :1 o including means forcoloring the light reflected from the third bulb.

3. In a lamp, a casing having a transverse partition and lightopeningsupon op ite sides of said partition, two light b s in said casinin rear of one of said openings, a color 15 ter in said partition, meansor preventing the light from one of said bulbs from shining through theopening in front thereof including a reflector suspended from saidpartition, and causing a portion of the rays of light from said lastmentioned bulb to be pro ected through said filter, a lamp bulb upon theother side of said partition, and a reflector projecting from the otherside of said partltion, and servin to direct rays of light from saidlast mentioned bulb in a predetermined direction, and also serving todirect in a predetermined direction the rais of light that have beenrejected throu the filter aforesaid by the mentioIne reflector. h f Ifix ntestimony w ereo a m si ature'.
